M10 – Barotraumas

Barotraumas is an aggressive action of pressure variations on the body.

In diving, barotraumatic aggression is due to the variation in the volumes of gaseous masses, air or other gases, enclosed in the cavities in the body. Therefore, barotrauma presupposes the existence of a cavity, enclosing a gaseous mass that is in communication with ambient pressure.

If the gases are contained in elastic or compressible compartments, such as the lungs, stomach or intestine, the walls of these organs easily adapt to volume variations. But if the compartments are not compressible, as is the case with the bone cavities, the air may conflict with the cavity that encloses it and cause the barotrauma.

BAROTRAUMA ARISES WHEN, FOR ANATOMICAL, PHYSIOPATHOLOGICAL CAUSES, OR BY TEMPORARY CHANGES, THERE IS OBSTRUCTION FREE OF PASSAGE OF GASES BETWEEN THE CAVITY WHERE THEY ARE CONTAINED AND THE OUTSIDE
